OF BROOKLYN, YORK WINDOW Application led July 21,

This invention relates to windows embodying a frame arranged for the slidable mounting of a pair of sashes therein to have movement one relative to the other, and wherein one side member of the window frame in which the sashes. are slidably carried is adapted to firmly impinge upon the face of the one side member of the sashes and to be bodily shifted with the sashes toward and be firmly impinged against the other side member of the frame to provide an airtight it between the window frame and sashes and thus obviating the necessity of applying weather strip or the like to the window frame, and which frame member is adapted to be released to permit of the easy adjustment of the sashes in the frame, and it is .the object of the invention to provide an improved constructed and arranged window of this character which is simple in structure, efficient in use, and easy to operate.

It is another object of the invention to provide improved means for mounting the sashes inthe shiftable side member of the window frame and provide means to exert a force on the shiftable member to retain the sashes firmly in the frame though readily and easily slidable therein and arranged to be automatically actuated when one sash member is moved to closing position to clamp the sashes in the frame against movement and to mount the sashes to have adjustment on vertical axes so that they may extend transversely and inwardly of the opening of the window to facilitate cleaning of the window. i

A further object of the invention relates to improved means for automatically locking the sashes against movement in a window frame either when adjusted to closed position or adjusted to various predetermined open positions, and to means for releasing said locking means-to permit of adjustment of the sashes, in the frame.

Another object of the invention relates to improved means in windows of this character for securing sash weight carrying cords or chains to the sashes.

Other objects and advantages will hereinafter appear.

yIn carrying out the embodiment ofthe invention illustrated in the drawings there is provided a, frame vcomprising a rigid top and side members 15, 16 and 17 and a rigid bottom sill 18 with a pair of light carrying sashes 19, 20, the .side frame member 16 being arranged with a longitudinal parting strip 21 to provide a pair of runways for the slidable engagement of one side member of the sashes, the outerwalls of said runways being chamfered, as shown at 16', and an edge portion of the sashes are correspondingly chamfered, as at 19 and 20 to provide a close fit between the sashes and runways.

The side frame member 17 is arranged with a' longitudinal channel 22 opening to the other side frame member 16 and has mounted therein a metallic casing 23 of channel shape in cross section, said casing being removably mounted in position by ,recessing the laterally flanged and curved extremities of the legs of the casing in the material of the frame member, as at 23.` The case is of a depth of about one-half the depth of the frame channel 22 and of a length slightly less than the frame member v17 extending from the sill 18 to a point within the top of said frame member,

tively, arrows,

which member extends somewhat above the.

top member 15, as clearly shown in Figure 1. A sash support in the form of a plate 24 of a length substantially the same as the casino" is 45 i ls)upported by a link 25 in the casing, said lmk e'ing in the form of a plate pivotally mounted at one end on a rod 26 extending transversely of and fixed at opposite ends in the legs of the casing, and pivotally mounted at the other end on a rod 27 extending transversely of the sash supporting plate land fixed at the'ends adjacent the top of said plate in laterally flanged portions 28 constituting slideways for a purpose to be hereinafter described. By 'the supporting of said sash sup-- porting plate by the link 25 the plate is adapted to have floating lmovement in a direction into and out of the casing. The sashes are mounted on the supporting plate 24 at the sides opposite to that at which they slidably engage in the runways in the frame member 16 to have sliding movement one relative to the other and have pivotal movement on vertical axes at said end of the sashes. For

this purpose the sash supporting platel 24 isoffset laterally intermediate the ends in a direction opposite to the flanges 28 to substantially channel shape in cross section, as at 29, to form a parting strip for the sashes and cooperate with the legs of the casing 23 to form a pair of sash runways. To slidably mount and retain the sash upon the supporting plate 24slideways 30 are fixed upon the face of said plate in the runways, said slideways comprising plates secured to the supporting plate intermediate the sides with the lateral marginal portions flanged, as at 31, and upon which flange portions auxiliary sash members 32 of channel shape in cross section are mounted, said auxiliary sash members having the marginal portions of the legs flanged inwadly, as at 33, for engagement over and in back of the flanged marginal portions 31 of the slideway plates 30. (F gures 1, 5, 6 and 7.) The connecting portion of the auxilliary sash members is offset inwardly for the en"- gagament of the outer face of the side members of the sashes 19, 20, as shown at 34 in Figure 14, to hold the light carrying and auxilliary sashes against lateral displacement one relative to the other, and the corners of the light carrying sashes are chamfered to fit correspondingly formed chamf'ered portions inthe inwardly offset connecting portion of the auxilliary'sash members tomake a tightfit between the two. The light carrying sashesare mounted in the auxilliary sash members 32 to have sliding movement with said auxilliary sash members upon the slideways 30 and-movement on vertical axes by angle members 35, one angle portion of which members is engaged in the end of and connected tothe connecting portion of the channel of the auxiliary sash members, and the opposite angle portion of one angle member engaged below the light carrying sashes and having a perforation therein for the engagement of a pivot secured in the li ht carrying sashes, as at 36 in Figure 10. he opposite angle portion of the other angles are Vengaged over 'the top of the light carr ing sashes and pivotally connected thereto y a pivot in the form of a headed screw 37 engaged in 'a perforation inthe angle and threaded into the top member of the sashes; (Figures 5 to 10, inclusiva) The angle mem- `bers for the upper sash are of greater length rection at right angles to the opening in the window frame. To adjust the light carrying sashes to such positions a lateral thrust is exerted on the sashes in a direction to move the sash supporting plate 24 into the casing 23 a distance to permit the ends of the sashes opposite to that at which they are pivotally supported in the auxiliary sash members to clear the runways in the frame member 16.

To prevent the sash supporting pivots from splitting the material of the sashes when made of wood due to the weight of the sashes or otherwise reinforcing members 38 are arranged in the sashes. -As shown in Figures 4 and 6 thesereinforcing members comprise metal strips folded upon themselves with the bend of the strip 0f circular form and the opposite ends divergiug outwardly therefrom and the extremities flared laterally. These members are driven into the sash with the curved bent portion positioned for the cngagement of the pivot screws therein, as

shown in full and dotted lines in Figure 6 and in dash lines in Figure 4. A modification of said reinforcing means is shown in Figures 8 and 9 as comprising rectangular sheet metal plates 38', having marginal portions flanged laterally, as at 39, for embedding in the material of the sashes, and having a perforation for the engagement of the pivot screw.

To counterbalance the' sashes 19, 2O counyterweights 40 are carried by chains or cords 41 secured at one end to the weights, which weights are arranged in the space between the bottom of the channel in the frame member 17 and the casing 23, and passed over plulleys 42 rotatably mounted on a pintle 43 xed at the opposite endsin avhood 44 fixed to the end of the casing 23, and extended through a spacer 45 for the rollers fixed;I in the hood. The opposite ends of the sash wei ht cords or chains are connected with the ang e members 35- for connecting the light carrying sashes with the auxiliary sash members. For this purpose ortions of the material of the angle mem ers 35 engaging in the auxiliary sash members are stamped therefrom at the bend of the angle members and extended laterally to form a laterally extending bifurcation at thev angle bend, as shown at 46 in Figure 3, and the angle portion from which said bifurcation portions are stamped has a portion stamped therefrom to form a slot 47 in line with the space between the bifurcation legs. To secure a sash weight cord thereto it is pinched together at a point within theend as by a pair of pliers and as shown at 41 in Figure 3, and such pinched together portion of the cord is engaged be'- tween the bifurcation legs with the extremity of the cord engaged in the slot 47. To retain the lightcarrying and auxiliary sashes against longitudinal displacement a portion at the ends of the auxiliary sash members is flanged over the sash supporting angles 35, as shown at 32 in Figure 3.

To firmly impinge the sashes 19, 20 against the frame member 16 and the sash supporting plate 24 against the sashes to provide an air tight joint and to prevent rattling of the sashes, the lsash supporting plate is in the nature of a clamping bar, and means are provided to yieldingly urge the plate in a 'direction outward from the easing 23 into engagement with the sashes and shift the sashes bodily therewith in a direction toward the frame member 16 but with an easy enough fit to permit of ready raising and lowering of the sashes. For this purpose yielding abutments or cushions are mounted on the con necting portion of and within the casing 23 in interposed relation to the casing and plate 24,

said abutments being shown as two in number and indicated by A and B, (Figures 1, 6, T, 1() and 11,) although a greater number may be used. Each of said abutments comprises a pair of coiled springs 48 seated at one end in a channel member,49 having the legs converging from an intermediate portion to one end (Figure 1) and at the commencement of said converging portion flanged laterally (Figure 6), and the opposite ends lof the springs seated in a channel member 50 of a width so that the legs thereof may be engaged over the flanges of the channel member 49 and the legs at one end flanged inwardly to engage over the flanges of said channel member 49 whereby the channel members are adapted to have an interlocking sliding connection, as at 51 in Figure 6, the end portions of the legs of the channel member 50 also converging toward the connecting portion and one end. The abutments are mounted upon the casing by securing'the channel member 49 thereon. In the normal position of the channel supportingplate 24 the abutments assume the position shown in Figure 10.

To shift :the sash supporting plate 24and sashes carried thereby toward the frame member 16 and firmly clamp the sashes in the fralne when adjusted to closed position yielding saddles are provided adapted to vbe interposed between the abutments and the sash supporting plate. These saddles comprise strips of yielding material folded upon themselves, as shown at 52 in Figure 10, and are carried by an actuator slide 53 `slidably mounted in the slideways 28 of the sash supporting plate, the slide being normally urged to position with the saddles as shown in Figure 10, by a spring 54 attachedat one end to a pin 55 extending transversely of and fixed at the ends in the walls of the plate offset f instance by the sash 2O by the bottom of said sash engaging a slide actuator 56 as the sash approaches its closed position, said slide acthe opposite end 57 offset laterally and eX- in the wall of the below the bottom the auxiliary sash which the sash 20 is connected.

tended through a slot 28 plate offset 29 to position of and for engagement by member 32 to When the sash 20 is moved to closing position the auxiliary sash member 32 will engage the laterally offset portion 56 of the slide actuator 56 and move the same and the slide against the tension of the spring 54 and interpose the saddles 52 between the abutments A and B and sash supporting plate 24 urging the latter on its link support 25 outward from t-he casing and therewith the sashes 19, 20 bodily toward the frame member 16 and firmly though yieldingly clamping and retaining the sashes in such position. When the sash 20 is raised the sash supporting plate will be released during the initial movement of the sash by the sash moving out of engagement with the offset 56 of the slide actuator 56, the slide being moved upward by its spring 54 and thereby moving the saddles 52 from between the abutments and sash supeans are provided to automatically lock the sashes 19, 20 in closed position or in various open positions, said means comprising a latch 60 pivotally mounted intermediate the ends on a stud fixed in the plate offset 29, as shown in Figures 11 and 13, said latch having pallets 61 extending laterally and oppositely from the opposite ends and adapted to' be projected through perforations in the walls of the `plate offset 29 and into recesses or sockets in the sashes, as clearly shown in Figures 1l and 13, this movement of the latch being effected by gravity and the aid of a counterweight 62 in the form of a rectangular plate fixed to the latch pivot at one corner. To release the latch to permit moving of the sashes to open position a manually operative latch actuator is provided comprising a cam member 63 formed on a plate 64 slidably mounted on a vertical stud 65 fixed in a bracket 66 in the form of a plate having the opposite ends flanged laterarally and in which flanges the stud is mounted, said bracket having tangs stamped therefrom and extended through openings in the connecting portion of the casing 23 and bent over the edge of said openings, as at 67, so that the bracket will lie contiguous to the casing. The actuator plate 64 has a reduced portion extended through a slot in the casing to serve as a finger'grip, or it may have a knob attached thereto as shown at 68. The latch actuating cam carrying plate is normally urged upward with the cam 63 to engage a cut out portion 69 in the edge of the plate by a spring 70 coiled about the stud 65 and confined between the bottom flange of the supporting bracket 66 and the cam carrying plate 64, in which position the cam will clear the projection at the lower corner of the plate 62 formed by the cut out in the edge thereof. In` order to release the latch the finger 'grip of the cam plate is grasped and said plate moved downward against the tension of the spring 70 causing the cam to engage the projection of the latchA plate 62 moving the same laterally, as shown in Figure 11, and the latch pallets outl of engagement with the sash recesses or sockets.

By the construction and arrangement of window as described it will be obvious that the sashes may be readily removed for replacing a light or otherwise by removing the pivot screws 37 and lifting the sashes to disengage the pivots from the 'perforations in the lower sash supporting angles 35, and that this may be done Without first removing a sash retaining strip as is usual. Furthermore, by the arrangement of the mounting of the casing or housing 23 the sash supporting plate 24 may be readily removed and another substituted therefor by withdrawing the same from the casing and removing one of the support pintles from 25, and that the entire casing 23 may be readily removed from the window frame without marring the framev and another substituted therefor.
